Q1: Which of the following cellular structures is responsible for protein synthesis?
A. Nucleus
B. Lysosome
C. Ribosome [CORRECT]
D. Golgi apparatus
Correct Answer: C
Rationale: Correct because ribosomes are the sites within a cell where genetic information is
translated to produce proteins, matching their primary biological function.
Q2: Calculate the value of x in the equation: 3x - 7 = 20.
A. 7
B. 8
C. 9 [CORRECT]
D. 10
Correct Answer: C
Rationale: Correct because adding 7 to both sides yields 3x = 27, and dividing by 3 results in x =
9.
Q3: Identify the sentence that uses correct grammar.
A. Their going to the store later.
B. Its a beautiful day outside.
C. They’re planning to visit the museum. [CORRECT]
,2
D. Your welcome for the help.
Correct Answer: C
Rationale: Correct because "they're" is the correct contraction for "they are," fitting the sentence
structure contextually.
Q4: In the human heart, which chamber pumps oxygenated blood to the body?
A. Right ventricle
B. Right atrium
C. Left ventricle [CORRECT]
D. Left atrium
Correct Answer: C
Rationale: Correct because the left ventricle is the strongest chamber and is responsible for
pumping oxygen-rich blood into the aorta for systemic circulation.
Q5: What is the primary function of the digestive enzyme pepsin?
A. To emulsify fats
B. To break down starches
C. To digest proteins [CORRECT]
D. To absorb water
Correct Answer: C
Rationale: Correct because pepsin is an enzyme in the stomach that specifically breaks down
proteins into smaller peptides.
Q6: If the pressure of a gas is increased while the volume remains constant, the temperature will:
A. Decrease
B. Stay the same
C. Increase [CORRECT]
D. Fluctuate randomly
,3
Correct Answer: C
Rationale: Correct because Gay-Lussac's Law states that pressure is directly proportional to
temperature when volume is held constant.
Q7: Read the following passage: "The depletion of the ozone layer is primarily caused by the
release of chlorofluorocarbons (CFCs) into the atmosphere. These chemicals destroy ozone
molecules, reducing the layer's ability to block ultraviolet radiation." Based on the text, what is
the direct result of CFCs?
A. Increasing global temperatures
B. Creating more ozone molecules
C. Reducing UV protection [CORRECT]
D. Causing acid rain
Correct Answer: C
Rationale: Correct because the passage explicitly states that CFCs reduce the ozone layer's
ability to block ultraviolet radiation.
Q8: Solve: 15% of 200.
A. 20
B. 25
C. 30 [CORRECT]
D. 35
Correct Answer: C
Rationale: Correct because calculating 0.15 multiplied by 200 equals 30.
Q9: Which bone is located in the upper arm?
A. Radius
B. Ulna
C. Humerus [CORRECT]
D. Clavicle
, 4
Correct Answer: C
Rationale: Correct because the humerus is the long bone of the upper arm that extends from the
shoulder to the elbow.
Q10: What is the pH of a neutral solution?
A. 0
B. 7
C. 7 [CORRECT]
D. 14
Correct Answer: C
Rationale: Correct because the pH scale defines 7 as the neutral point, representing a balance
between acidic and basic (alkaline) properties.
Q11: Select the word that best completes the sentence: "The patient's condition was _______; he
improved slightly then worsened again."
A. Stationary
B. Constant
C. Fluctuating [CORRECT]
D. Stable
Correct Answer: C
Rationale: Correct because "fluctuating" accurately describes a state of irregular change,
matching the context of improvement followed by decline.
Q12: Which part of the brain controls balance and coordination?
A. Cerebrum
B. Medulla oblongata
C. Cerebellum [CORRECT]
D. Thalamus
